Hi,

The following vulnerability was published for inetutils, the CVE
description on MITRe might be missleading as it indicates it is
somehow related to Juniper only. But see other refernces, [1] and [2].

CVE-2019-0053[0]:
| Insufficient validation of environment variables in the telnet client
| supplied in Junos OS can lead to stack-based buffer overflows, which
| can be exploited to bypass veriexec restrictions on Junos OS. A stack-
| based overflow is present in the handling of environment variables
| when connecting via the telnet client to remote telnet servers. This
| issue only affects the telnet client — accessible from the
| CLI or shell — in Junos OS. Inbound telnet services are not
| affected by this issue. This issue affects: Juniper Networks Junos OS:
